...researchers have reprogrammed human induced pluripotent stem (iPS) cells into the cells that eventually become eggs and sperm... theoretically, an infertile patient's skin cells, for example, could be taken and reprogrammed into iPS cells, which, like embryonic stem cells, have the ability to become every cell type in the human body. Those cells could then be transformed into germ-line precursor cells that would eventually become eggs and sperm... a man with a low sperm count, for example, may be able to have more of his own sperm generated to fertilize his partner's egg.
But a man with a low sperm count getting extra sperm generated from his somatic cells is among the least interesting applications of this technology. Some alternative applications:
- A lesbian could have sperm made from her cells to fertilize her partner.
- A gay man could have eggs made from his cells to be fertilized by his partner. Note that this would require a surrogate mother to bear the child, at the cost of tens of thousands of dollars. At least until artificial wombs are invented - probably a more difficult task than making germ cells from random adult cells.
- A heterosexual woman could have sperm made from her cells to fertilize her husbands eggs. Seems kind of pointless, but it would get you 15 minutes of fame, or at least a PhD in Transgressive Art at Yale.
Men would no longer be essential for society's survival (women would still be necessary until we have artificial wombs). There's no obvious reason why female separatist communities couldn't thrive, instead of slowly physically dying out. The next generation would be conceived with this technology - and it would, of course, be all female - no Y chromosome would be involved.
Could they have an fitness advantage over hetero couples? Women seem to take more to child-rearing than men, and since both women in the couple have wombs, they can both be pregnant at the same time. The children would all be daughters, and if women are the reproductive bottleneck, that bottleneck just got bigger, if they want it to. How would the daughters of two helicopter moms turn out?
It would also give hope to older women. A 50 year old female careerist would have the option of hiring a surrogate, leveraging the money she has made into children instead of an extravagantly appointed empty house.
This technology will not be ready this year or next year, but I expect to live to see it (I'm not particularly techno-optimistic like some people, but this technology really doesn't seem that far-fetched).
